svn commit: r277823 - head/sys/dev/ath/ath_rate/sample

New Revision: 277823
URL: https://svnweb.freebsd.org/changeset/base/277823

Log:
  Cast everything to something longer than 32 bits so the sample mask
  doesn't get truncated to 32 bits.
  
  Without this, 3x3 NICs transmitting at an MCS rate whose rix (rate
  index) in the rate table is > 31 end up returning errors, as the
  sample rate code doesn't think the rate is set in the rate table.
  
  Tested:
  
  * AR9380, STA, speaking 3x3 to an AP
